Question

Statement I: When a finely divided active carbon or clay is stirred into a dilute solution of dye, the intensity of colour in the solution is decreased.

Statement II: The dye is adsorbed on the solid surface.

Prashant Kotian · Accepted Answer

Correct answer: A. Dilute dye solutions lose colour intensity when stirred with active carbon or clay because the dye molecules are physically adsorbed onto the high surface area of the solid adsorbent. Thus, both statements are correct, and Statement II is the correct explanation.
